Mold-damaged grain sorghum as a diet for three stored-grain beetles (Coleoptera)
Environmental Entomology 12 (2), 558-560
Abstract: Three species of stored-grain beetles, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), Cynaeus angustus (LeConte) (Coleoptera: Tenebrionidae), and Cryptolestes pusillus (Schonherr) (Coleoptera: Cucujidae), were reared on flours prepared from grain sorghum stored with increasing levels of moisture and, therefore, different degrees of invasion by storage molds. Flours from sorghum molded by the Aspergillus glaucus group and by the A. candidus group were better growth media for all beetles than flour from the sorghum control. Grain additionally invaded by Penicillium citrinum Thom inhibited growth of T. castaneum and caused 100% mortality in C. pusillus but supported larval growth of C. angustus as well as the control. Reproduction of T. castaneum was enhanced on all mold-damaged flours; progeny per female of C. pusillus increased on flours supporting increased larval size.
